LASTING-YMACHINE.

SPECIFICATION forming part of Letters Patent No. 251,430, dated December27, 1881.

Application filed April 30, 1877.

To all whom it may concern:

Be it known that I, CHARLES W. GLIDDEN, of Lynn, in the county of Essexand State of Massachusetts, have invented an Improved.Lasting-ll/Iachine, of which the following is a tween the toe and heel,at each side, are ar-- ranged side-lasting devices, shown as-composed-of fingers. These fingers are arranged to turn upon their axis, torise and fall, and to be adjusted horizontally to adapt them to thecurve of the last-bottom. The machine in its organization includes abelt or girth adapted to act gradually upon the vamp and stretch anddraw it about the last, and cooperating therewith are toe and heel-andside lastiugdevices, adapted to bear the edges of the upper (thenstretched about the last and held by the girth or band) horizontal yover upon the innersole. At the commencement of this operation thebottom of the last and the fingers or side-lasting devices and the heeland the toe lasting plates occupy such position with relation to eachother that the bottom of the last rests at a level above the level ofthesaid sidelasting devices and toe-lasting plates; but at the completionof the operation the sole occupies aplace brlow the said devices. Thegirth is so held and operated as to touch the vamp substantially on, at,or near a linedrawn from the toe along the vamp, covering the top of thefoot portion of the last, (a line denomi nated by me as themedia-nlinefl) andto thereafter bear with greater force upon the saidvamp from t-he'said median line tothe edge of the lastbottom, therebygradually drawing the vamp from the said median line toward the edge ofand fitting it to the last, after which the edges of the upper,projecting above the last and inner sole, are turned over upon the innersole by side-lasting and heel and toe lasting devices.

Figure 1 represents in side elevation a machine embodying my invention;Figs. 2 and 3, end views thereof; Fig. 4, a plan with the side and heeland toe lasting devices at their innermost positions Fig. 5, a form ofarm to support the belt; Fig. 6, a. section showing side and shanklasting mechanism Fig. 7, a detail showing one form of the elasticportion of my belt or girth Fig. 8, a detail of the device for holdingthe heel of the upper against the heel of thelast; Fig. 9, a detail ofcam h and disk '0'; and Figs. lOand 11, forms of belts or girths, to behereinafter described.

The frame a of the machine is of suitable shape to properly sustain theworking parts. The driven shaft b, operated by a belt upon pulley c, hasa pinion, d, that engages a toothwheel, 0, on the'main shaft, whichlatter rests in bearings f, and has attached to it a camgrooved hub, g,a cam, h, and a disk, a, provided on its periphery with a toe, j, and onits face with a pin and roller, 70. The cam g operates the lever l,provided with an elongated central slot m, that receives afulcrum-block, a, mounted loosely on a stud, 0, made verticallyadjustable with the block in the slot 1), to change the fulcrum of thelever l and alter the throw of its upper end, and of the sliding head r,adjustably connected by the screw 8 with the carriage t, which is thusreciprocatedby this lever. This carriage it, moved in guidways n, has aconcave upper face, to which is fitted the convex lower surface of aframe, '1), adjustably attached thereto by set-screws 20. These concaveand convex surfaces permit the frame n, with its attached devices tolast the toe, to be adjusted in the arc of a circle to place thetoe-plate 2 in such position with relation to the toe of the last as tomove over it, whatever may be its curvature.

The toe-platesare of such shape that when closed their edges conform tothe shape of the toe ofthe last, the plates, when closed, lapping overthe lastand inner sole. These plates are attached at the ends of leversw y, the former pivoted at 4 and the latter at 5. The plate of I00 eachlever operates upon that side of the toe opposite the side of the toe atwhich its lever is pivoted. This construction enables the plates tosweep from a point outside the last toward its center, at an angleapproximating forty-five degrees, which permits the upper to be drawnevenly and very close at the toe, and at the sides of the last near thetoe, over the edge of the last, thereby drawing in the upper toward thecenter of the last.

The levers any are connected by links 7 with pins on a hand lever, 8,having its axis at 9.

- forward into the position shown in Fig. 4. Af-

ter the shoe is lasted the cam gand lever lact to move the carriaget andits attached devices a little in the direction of the arrow, Fig. 4, andthen the operator moves the lever 8 and withdraws the toe'lasting platesfrom the toe, and at the same time the link 11 acts to move forward thetoe-wiper 13 beyond the edge of the separated plates 2. Just before thenext shoe is to be lasted the carriage t is moved forward to place thetoe-wiper in line with the toe of the last, so that the upper at the endof the toe will strike against the wiper, and be drawn by it closely andsnugly over the last, just before the toe of the last comes into theseat 14, andjust before the plates 2 are operated or moved forward topress over the edge of the upper, as before described.

By means of the screw 8 the toe-lasting devices may, for lasts ofdifferentlen'gths, be removed more or less from the last supporting pin.The cam h (see Fig. 2) strikes the lower end of the lever 18, carryingthe head-19,.provided with the longitudinally and vertically adjustableand rocking fingers 20, constituting the side-lasting devices. Thesefingers are preferably curved, and roughened attheirouter ends to engagethe upper and retain their engagem'ent with it as they are moved towardthe center of the last. Fig. 6 shows a finger and head in end view.

The shank of each finger is fitted to an ad justable holder, 21, whereit is confined by a set-screw, 22, the latter permitting the lower faceof the finger to be placed at the proper level to correspond with thatsurface ofv the last immediately above or over which it is to work.These holders 21 have stems fitted into sockets in the head, where theyare adj ustabl y held by set-screws 23, they permitting the fingers tooccupy such positions with relation to each other and the surface of thebottom of the last as to conform to the curved and other portions of thelast from its toe to its heel.

The longitudinal adjustment of the fingers in the holders permitstheforward acting edges of the fingers to be placed in a line to conformwith the outline of the edge of the last, whereby all the fingers mayoperate upon the upper simultaneously, or, if desired, sooner at someportions thereof than others. So, too, by adjustments of the fingersopposite the shank of the last, they may bemade to move to a pointnearer the center of the last than the other fingers, therebyfacilitating lasting the shank closely, this being of special servicewhen lasting rights and lefls. The opposite head, 24, mounted on lever25, has a set of fingers like those described as moving with head 19.Lever 25 is vibrated by means of a pin, 17, projecting from the innerface of disk 2'. (See Figs. 2 and 9.) These fingers are not movedhorizontally forward to crowd or push the edges of the upper over theedge of the last until after the bottom of the last occupies such aposition with relation to the fingers as to be lower than the fingers.Then the fingers close over the last. The notches at the ends of thefingers permit tacks to be driven back from the ends of the fingers.These notches may be of more or less length, long notches beingpreferably employed in the fingers, especially at the shank, to permitthe tacks to be driven back from the center of the shank.

The arm 32, having its fulcrum at 33, has

its forward end, fore and back part downholds or pressers, 34-. 35,shown as adjustably a ttachedthereto, and adapted to bear upon the heel,and the forward or toe portion of the last or inner sole thereon, toseat the last and its upper upon the toe-rest or other support for thelast, and place the bottom of the last at the proper level for thecorrect operation of the side and heel and toe lasting devices. When thecarriage is descending and the bottom of the last and side-lastingdevices are being brought to such level as to permit the sidelastingdevices to be moved horizontally over and beyond the edge of the lastand toward itscenter, the arm 32 is held rigidly by the pawl 36, it thenengaging a notch, 37, in a link, 38, connected with a stud or pin, 39,fitted in a slot, 40, at the rear end of arm 32, the opposite end of thelink being connected with a hand-lever, 42, moved in one direction by aspring, 43. The arm 32, held rigidly, causes the fore and back partpressers or downholds 34 35 to press upon and position the bottom of thelast. After the side-lasting devices have completed their inwardmovement a pawl-litter, 44, frees the pawl 36, permitting the spring 43to throw back the lever 42 and the stud 39 from above the bracket 41. Atthis stage of the operation the parts are as in Fig. 3. R0- tation ofthe main shaft from the position shown in Fig. 3 will draw the side andthe toe lasting devices away from the last and upper and lift the.carriage, it carrying with it the jack 45, having a lever, 46, pivotedto it at 47.

The lever 46 is provided with a hinged lastholding pin, 48, (shown indotted lines Fig. 2,) which is held upright by a spring, 49, pressingupon a headpiece forming part of the pin 48 below its pivot. As thecarriage and jack are lifted the last is also lifted above the side andthe toe lasting devices, and the arm 32 is then thrownover backward onits pivot 33, when the last may be removed and another shoe and vIIOmoval of the last and shoe.

last be substituted for it. A screw, 50, on the jack permits theadjustment of the lever 46 thereon to place it and the last-holding pinat the proper position with relation to the heellasting devices, to thuscompensate for variations in position with relation to the heel of thelast of the hole made therein for the reception of the lastholding pin.1

' The jack is supported upon a rod, 51, provided at bottom with ascrew-thread, 52. The screw-thread 52 is engaged by an inclinedscrew-thread ofa bevel-pinion, 53, which is engaged by a bevel-gear, 54,on a shaft, 55. The shaft 55 is adapted to be operated by hand to rotatethe pinion 53 when it is desired to raise or lower the rod 51 and placethe top of the jack-lever 46 and the last thereon at the proper heightwith reference to the devices to operate upon the edge of the upper. Aslide, 56, is lifted by the toej, (see Fig. 1,) and acts against the endofan adjustable screw, 57, of the jack, just as the side, heel, and toelasting devices are fully contracted, to lift the jack a little andpress the turned-over edge of the upper and inner sole and last closelytogether, a portion of the eamegroove in the cross-head 2S afl'ordingsufficient space to permit the movement of the carriage upwardindependently otthe roll it.

A bracket, 58, on the carriage 29, has pivoted to it a lever, 59,provided at its top with a concaved seat, 60, to which is fitted ablock, 61, having pivoted arms 62 63, provided with heel-lasting platesor slides 64 65, adapted to operate with reference to the heel,substantially as described, of plates 2 in connection with the-toe.These pivoted arms 62 63 are provided with friction-rollers 64, that actupon inclines 65 on the heads 19 and 24, when they are closed, and whilethe lever 59 moves in the direction of the arrow in Fig. 1, therebyoperating the arms and moving the plates against the edge of the upperat the heel, so as to turn such edges over at that point. As thecarriage rises the lower end of the lever 59 passes above the roller 66,and the spring 67 moves the lever 59 and the heel-lasting portions awayfrom the heel of the upper and last, to permit the re- As the carriagedescends, the inclined outer surface of the lever'59 also meets theroller 68, and it and the roller 66 force the lever forward, so that aheelholder, 69, composed ofa-piece of metal curved to the shape of theheel end of the last, and connected with a piece of rubber, 70, ispressed closely against the upper on the heel of the last just before oras the toe of the vamp or uppers is being wiped or rubbed by thetoe-wiper, and

just in advance of the action of the heel-plates kept pressed closely incontact with the upper on the last by a portion, 71, herein shown ascomposed of indie-rubber of suitable shape to assist in pressing theinelastic portions 91 against the upper as the last is forced down bythe downholds or pressers acting on the inner sole on the bottom of thelast. The inelastic portions 91 are so shaped and held as to first comein contact with the upper on the last substantially at or near thismedian line, and then to gradually move along over and stretch and pressand draw and fit the upper closer and closer to the las drawing it fromthe median line toward the opposite edges of the inner sole, and holdingit until after the action of the sidela'st-ing devices upon the edge ofthe upper, they sliding over the last opposite and at or near the end ofthe girth, it terminating at or near the level or line of action of theside lasting devices.

' Fig. 11 shows in' elevation a form of girth which I prefer to use. Thesaid girth is shown as composed of a yielding portion, 71, and ofportions 91, of leather, canvas, or practically inelastic material, tobear directly against the reference to the upper, and it thus developsan amount of friction and consequent drawing and stretching on the upperwhich it could not attain it' it touched only at one point or over ashort area, while at the same time the constant pressure which it exertsover the whole length of both its elastic and inelastic portionscontinually presses the upper against the last, and prevents the upperfrom slipping back, by accident or otheruise,and losing the stretch so'obtained. The force of the friction exerted by the inelastic portionsof the girth is measured by theupwaid pressure of the snpporton whichthe said inelastic portions rest, or the elasticity of the elasticportions of the girth.

Fig. 7, in end view, shows the elastic portions 71 ol'a beltor girthstretched across hinged arms 72, which may be provided each with apivoted dog, 73, as in Fig. 7, or with a roller, 74, as in Fig.5. Fig.10 sh'ows a modified form of girth which I devised, but do not hereinclaim, as I have made it the subject-matter of another applicationdivided off from this one, andfiled June 6, 1879.

The central portion, 90, of this girth, Fig. 10,

is thickened transversely to bear against the act level with relation tothe side-lasting and heel and toe lasting devices. The arms carrying thetoe-plates or toe-lasting devices would be operated at suitable times.

In the operation of this my present machine it will be noticed that thebottom of the last, at the commencement of the lasting operation,occupies a certain relative position with rela= tion to the side and thetoe lasting mechanisms or devices, and that at or near the completion ofthe stretching and drawing operation of the inelastic portions of thegirth upon the upper the bottom of the last occupies a differentrelative position therewith-viz., a position such that the side-lastingdevices and heel and toe lasting devices are above the plane of thebottom of the last, and the last is automatically and mechanically heldin a fixed position at the level predetermined for it to occupy beforethe side-lasting devices or toe and heel lasting devices operate to laythe edges of the upper over upon the inner sole on the bottom of thesaid last.

I am aware that a sole-shaped plate held at or near its center has beenlaid upon theinner sole on the last, and by a foot-operated treadle hasbeen made to bear the last and upper thereon down while being lasted, soI do not claim a presser orholddown,except when each is made separatefrom the other, and each bears only upon a small portion of the innersole before and back of its shank.

I am aware thatlasting-machines were made by Shailer and Ethridge in1862 and 1863, which machines were put in evidence in the interferencecase wherein myself and said Shailer and Ethridge were parties, and I donot claim the things contained in said machines which were introduced inevidence in that interference case, such things being public property;but
